I am trying to add a VPN to my Raspberry Pi NAS, that I have created, so I can access it away from home while still securing my network.

I am currently going through the OpenVPN for Docker walk through: https://github.com/kylemanna/docker-openvpn/blob/master/README.md and when I try to run the following command:

docker run -v $OVPN_DATA:/etc/openvpn --rm kylemanna/openvpn ovpn_genconfig -u udp://VPN.SERVERNAME.COM

I get this error:

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/a                                                                                                   rm64/v8) and no specific platform was requested
exec /usr/local/bin/ovpn_genconfig: exec format error

and when adding --platform linux/amd64/v8

I just get:

exec /usr/local/bin/ovpn_genconfig: exec format error.

NAS Build: Raspberry Pi 4 (128 GB SD, 8 GB RAM), External HDD 1 TB, Rasbian OS lite 64, and Open Media Vault as my NAS OS.

Is there a way I can fix this so the command goes through, or isn't this a viable option to secure my home NAS?

    You are trying to run something for an Intel CPU. The Pi is ARM

  • Would changing --platform to ARM solve this issue? sudo docker run -v $OVPN_DATA:/etc/openvpn --rm kylemanna/openvpn ovpn_genconfig -u udp://ausrbp01a.duckdns.org --platform linux/arm64/v8

  • Now I'm getting "docker: invalid spec: :/etc/openvpn: empty section between colons."

  • Even after fixing the invalid spec error and specifying the CPU to arm64 it looks like it still won't work since this isn't meant for a PI CPU.
